基于硬件控制的双通道机载雷达数据记录仪

摘要

针对总线控制的高速大容量雷达数据记录仪存在着操作系统不稳定、数据传输速率受限、成本高等问题，提出了基于硬件控制的双通道机载雷达数据记录仪。记录仪采用板卡形式实现功能独立的两路雷达数据记录模块，利用硬件控制单元作为中央控制器，管理控制两路数据的实时存储。整个系统采用硬件实现智能通信，无需搭载任何操作系统。对整个装置分别进行了地面模拟和无人机搭载试验测试，测试结果表明：基于硬件控制的双通道机载雷达数据记录仪能够实现两路高速雷达数据的记录工作，保证了数据记录的实时性与可靠性。%High-speed and large capacity radar data recorder based on bus had the problems that the operating system was unstable,data transfer rate was limited,and the cost was high.A dual channel airborne radar data recorder based on hardware control was designed to solve the problems.In this recorder,boards were made to realize two-way radar data record module,each of which had independent function.Hardware control unit was used as the central controller to manage and control the real-time storage of two-way data.The system used hardware to complete intelligent communication without any operating system.Ground simulation and uavs tests were conducted for the whole device.Test results showed that this recorder could complete the record of two-way high-speed radar data,which ensures the real-time and reliability of data record.
